Exchange interactions and spin states in a V15 magnetic molecular nanocluster

Abstract

Magnetization reversal in a V15 magnetic molecular cluster is studied theoretically and the results of calculations are compared with the available experimental data. Analytical and numerical methods (e.g., a modified Lanczos method) are used for calculating the energy spectrum of the cluster and for determining a set of exchange constants, which ensures good quantitative agreement between the results of theoretical calculations and experimental data on the behavior of magnetic susceptibility in the range of weak as well as strong fields. The fine structure of transitions from a low-to a high-spin state is predicted (in the range of ultrahigh fields, each of three transitions is a combination of two close transitions).
